Maximum-likelihood trees depicting the phylogenetic relationships of CP (a) and Rep (b) of BFDV. Lineages supported by significant bootstrap values are bracketed. The CK, LB, and LK lineages within the Rep phylogeny (marked with an asterisk) were previously described by Ritchie et al. (22) and refer to the group of host species associated with the genotype: CK, cockatoos; BG, budgerigars; and LK, lorikeets. The LB lineage described here similarly refers to the host species associated with the genotype: LB, lovebird.
